ATLANTA – The largest number of speakers in Atlanta City Council history attended Monday’s council meeting.

The speakers were part of Atlanta’s May Day march, and they crammed into the city council chambers to protest Georgia State University’s plans to develop Turner Field and its surrounding neighborhoods; and in support of the environment, workers’ and immigrant rights; and other topics.

During the meeting City Council president Caesar Mitchell confirmed that Monday's roster of attendees who had signed up to speak was indeed the largest in council history.

Besides Atlanta, May Day marches were held across the nation on Monday, drawing protestors against President Trump’s immigration policies and in support of what they said were worker’s rights.

In past years, May Day, also known as International Workers’ Day, has spawned demonstrations around the world.

Loads of demonstrators from across Wisconsin arrived in Milwaukee Monday morning to protest for better pay and better working conditions.

Hundreds gathered in Union Square in New York City, carrying signs in support of Black Lives Matter and pro-immigration policies.

About 1,000 teachers in Philadelphia and some parents marched in protest of working nearly four years without a contract and five years without a pay raise.

Hundreds descended on Houston’s city hall, rallying for workers’ and immigration rights.
